3 Wire Speed Sensor
| Pin | Symbol | Usual Wire Colour |
|---|---|---|
| 1 | IGN | Yellow (Y) |
| 2 | Red (R) | |
| 3 | SP1 | Light Blue – Red Dash (L-R) |
Where is the output speed sensor located?
Locate the speed sensor. The sensor is found on the bottom of the transmission and can be identified as a small plug that is sticking straight out of the transmission with an electrical connector plugged into it.
How does 2 wire speed sensor work?
First off is testing the 2 wire speed sensor. These sensors are self powered, meaning the revolutions inside the case generate the signal needed to create movement in the speedometer. Using the drill to operate the sensor shows that as the RPM’s of the drill increases, the voltage output of the sensor increases.
What does a output speed sensor do?
Function. The output speed sensor measures how fast a vehicle moves and sends that information to other vehicle systems. The transmission control unit uses the speed to determine when to change gears, adjust the torque converter and display the vehicle’s speed in the speedometer.
Where is my vehicle speed sensor wire located for?
The other 2 are not used but the VSS wire is the brown wire located on the larger of the 2 connectors not being used. In addition to the standard power and ground leads, remote-mount navigation (and even some in-dash units) systems connect to a vehicle’s Vehicle Speed Sensor (VSS) wire.
What kind of wiring does a speed sensor need?
Includes (VSS) vehicle speed sensor wiring, transmission wiring (if applicable) and. Input Speed Sensor, Trans, 4L60E to 4L80E This harness is designed to be a complete wiring system for the fuel injection system used on General. It’s getting the Speedometer sensing from a wire from teh PCM (LS1 / 4L60e tranny).
How can I test the transmission speed sensor?
Place bucket or oil drain pan underneath the sensor, there will be some oil that drains out. Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling. Turn the key to the ignition on, but engine off, position (one key click past Accessory)
When does a wheel speed sensor start to work?
Most wheel speed sensors (except for the latest generation of “active” WSS sensors) won’t generate a readable signal until a vehicle is traveling 3 to 5 mph or faster. You can spin each wheel by hand to see if the WSS is generating a signal, but that won’t tell you if the signal is accurate or how one WSS compares to another.
